For hydreigon try for timid or modest. When it comes out, give hudreigon choice specs

Give marshadow a life orb.

How about using aegislash. Either go weakness policy mixed tank or standard swords dance set. Aegislash and hudreigon work well together as they both cover each other’s weaknesses. If your dealing with an unfavourable matchup you could easily switch between the two.
